DYEING AND LIKE MACHINE.

Application filed May 7, 1924.

To all whom it may concern.

Be it known that we, Isaac MITCHELL and GEORGE HERBERT lVoRnswon'rH, subjects of King George V of Great Britain, residing, respectively, at Brockholes, near Huddersfield, in the county of York, England, and Horsforth, near Leeds, in the county of York, England, have invented a new and useful Improvement in Dyeing and like Machines, of which the following is a specification.

The invention has reference to dyeing and like machines for treating textile fibres in the form of tops, and has for its object to provide an improved construction of machine which will enable the treatment to be expedited, and more uniform results obtained.

The characteristic features of the improved machine are that instead of the liquid being caused to pass through the balls of tops in an axial direction as is usual in the known top dyeing machines, it is caused to pass through them in a direction at right angles to the axis about which the balls are coiled, and that the machine is so constructed that the dye or other liquor can be forced positively through the material in one direction and be drawn or allowed to percolate by gravity through the material in the opposite direction.

The invention will be described with reference to the accompanying drawing in which Figs. 1 and 2 are, respectively, a transverse section and a plan view of the improved machine, the means for effecting circulation of the liquid being omitted, since they form no part of the invention.

Referring to the drawing a trough or vessel 64 is divided by a partition 7) into two longitudinal chambers each of which is connected by a pipe 0 or d to the liquor circulating pump or other means. In one of the chambers and extending from end to end of same a trough is formed, in this instance by two side members 6, 6, having at a suitable point in their height inwardly extending ribs or flanges 6 0 to support a curved plate or preferably a series of curved plates e forming the bottom of the trough. The centre part of the plate 6 is perforated for a suitable width as at 6 The walls of the side members are shown as being vertical, but they may be curved or Serial No. 711,609.

dished outwardly above theplate a if preferred.

A longitudinal lid or cover is provided for the trough in the form of a number of sections f hinged at f and adapted to rest upon the upper edges of the side members e. These sections 7' are curved, as shown in Fig. 2 and the centre part of each section is perforated for a suitable width as at 7" in the same manner as the base plates 6 The outer edges of the lid sections may be recessed as at f to take over upstanding lugs e or one of the side members e, such lugs having longitudinal openings such as 7 to receive pins for the purpose of securing the lid sections in closed position.

The balls of tops, indicated at g are placed end to end in the container or trough, as shown in Fig. 2, to completely fill same, any slight compression which may be necessary to insure a good fit against the trough ends resulting in a slight increase in diameter of the balls for which ample width is avaliable laterally, and which is rather advantageous than otherwise.

The dyeing is normally or principally effected by forcing liquor upwardly through the trough. When the liquor is so forced, upwardly, the peripheries of the balls will engage or bear against the unperforated side walls of the trough and against the unperforated side portions of the lid sections and form an adequate seal to compel the liquid to pass through the body of the ball.

When the direction of flow or circulation of th liquor is reversed as is desirable to ensure perfectly even dyeing, the balls seat themselves against the base plates and, as before, a seal is formed which compels the liquid to pass completely through the bodies of the balls.

The horizontal disposition of the trough enables the vessel in which it is placed to be relatively shallow in depth, thereby facilitating access for insertion and removal of the balls.

Two, three or more troughs may be employed side by side, with a common lid or with common lid sections or with individual lids If two on four troughs are employed the boiling up chamber of the vessel is preferably disposed centrally instead of to one s ide as shown. The liquid is forced in through the pipe 0 and passes upwardly through the holes in the bottom, through the goods, and through the holes in the lid. Th action is then reversed, and the liquid is caused to flow downwardly in, the reverse direction into the pipe 0. The liquid is caused to flow up and down alternately through the goods until they have received sufiicient treatment.

The troughs and the lids or covers are preferably made of or coated with a material whichwill not be affected by the liquor employed.

Having thus described our invention, what weelaim new and desire to secure by Letters Patent is 1. A dyeing machine, comprising a. trough for holding the goods having a downwardly curved bottom and an upwardly curved top, said bottom and top being perforated at their middle parts and having imperforate side portions which form seats which constrain the liquid to pass through the body of the goods, and means for passing liquid up and down alternately through the bot tom and top and the goods between them.

2. A dyeing machine as set forth in claim 1. the said trough having side plates provided with lugs'upon which the bottom is removably supported, and the top being K hinged to one of the side plates.

In testlmony whereof we affix our s1gnatures.
